One cold Christmas day, Kyon heads over to school and the SOS Brigade's holiday celebration, only to realize that Haruhi Suzumiya seems to have disappeared. Moreover, no one even remembers her or the SOS Brigade; Mikuru Asahina knows nothing and is now afraid of him, and Itsuki Koizumi has also gone missing. The Literature Club, formed only by an uncharacteristically shy Yuki Nagato, now occupies the old SOS club room.

Suzumiya Haruhi no Shoushitsu is based on the fourth light novel of the acclaimed Haruhi series and is set after the events of the anime series. Not uncultured in the supernatural, Kyon will have to deal with his whole life turned upside down like a bad joke, and maybe it's better that way.

Yuuta Hibiki wakes up in the room of Rikka Takarada and notices two things: he has no memories, and he can hear a mysterious voice calling his name from a nearby room. On further inspection, he finds a robot—which introduces itself as Hyper Agent Gridman—behind the screen of an old computer. Much to Yuuta's surprise, Rikka cannot hear Gridman, nor can she see the ominous monsters looming over a thick fog as it envelopes the town outside. Another giant monster materializes in the city and proceeds to wreak havoc. Amidst the confusion, Yuuta is once again drawn to the old computer and merges with Gridman. Suddenly, he appears in the middle of the battle and is forced to fight the monster. Together with Rikka and fellow classmate Shou Utsumi, Yuuta forms the "Gridman Alliance" to defeat the monsters plaguing the city and find whoever is responsible for their emergence.

The map is not all they come across; they also manage to come into contact with the straw hat pirates. After a short battle, Luffy and company are robbed and separated from one another. Now they must find a way to make it to the island before El Drago does and take the legendary treasure for themselves.
